Summary of Key Issues
BreastScreen Australia data are highly relevant and timely for monitoring trends in breast screening participation and the detection of invasive breast cancer and ductal carcinoma in situ (DCIS) through BreastScreen Australia. A relatively small amount of screening mammography occurs through services other than BreastScreen Australia.
BreastScreen Australia is Australia’s national, population-based breast cancer screening program and is a joint program of the Australian and state and territory governments.
Australian Institute of Health and Welfare (AIHW) is a major national agency set up by the Australian Government under the Australian Institute of Health and Welfare Act 1987 to provide reliable, regular and relevant information and statistics on Australia's health and welfare. It is an independent Commonwealth entity established in 1987, governed by a management Board, and accountable to the Australian Parliament through the Health Portfolio.
The AIHW aims to improve the health and wellbeing of Australians through better health and welfare information and statistics. It collects and reports information on a wide range of topics and issues, ranging from health and welfare expenditure, hospitals, disease and injury, and mental health, to ageing, homelessness, disability and child protection.
The Institute also plays a role in developing and maintaining national metadata standards. This work contributes to improving the quality and consistency of national health and welfare statistics. The Institute works closely with governments and non-government organisations to achieve greater adherence to these standards in administrative data collections to promote national consistency and comparability of data and reporting.
One of the main functions of the AIHW is to work with the states and territories to improve the quality of administrative data and, where possible, to compile national datasets based on data from each jurisdiction, to analyse these datasets and disseminate information and statistics.
The Australian Institute of Health and Welfare Act 1987, in conjunction with compliance to the Privacy Act 1988, ensures that the data collections managed by the AIHW are kept securely and under the strictest conditions with respect to privacy and confidentiality.
For further information see the AIHW website www.aihw.gov.au.
The AIHW has been receiving BreastScreen data since 1996.
BreastScreen data are available within about 6–12 months. (It can take up to 12 months for final pathology results on all breast tissue samples to be received by BreastScreen registers.) The BreastScreen Australia database cannot be fully compiled until the final jurisdiction supplies its data.
BreastScreen Australia data are published annually in the BreastScreen Australia monitoring report available on the AIHW website where they can be downloaded without charge. Supplementary data tables presenting data that are more detailed accompany each report, and these are also available on the AIHW website where they can be downloaded without charge.
While many concepts in the BreastScreen Australia monitoring report are easy to interpret, other concepts and statistical calculations are more complex. All concepts are explained within the body of the report presenting these data, along with footnotes to provide further details and caveats. The appendixes provide additional detail on the data sources and classifications, and on the statistical methods used.
Breast cancer screening data are highly relevant for monitoring trends in breast screening participation and the detection of invasive breast cancer and DCIS, as well as other measures of program performance such as recall to assessment rates and sensitivity measures. The data are used for many purposes by policy makers and researchers, but are supplied and analysed specifically to monitor and inform BreastScreen Australia.
All data provided by state and territory BreastScreen programs, once analysed, are supplied back for verification.
BreastScreen data are reported and published annually by the AIHW.
